SPECIFICATION forming part of Letters Patent No. 259,606, dated June 13,1882,

Application filed Murch 1,1881. (ModeL) Be it known that I, GILBERTTOWNSEND, 2d, a citizen of the United States, residing in the town ofLodi, Seneca county, New York, with post-office of Townsendville, haveinvented an Improved Framing-Rib or Corner-Piece for the Construction ofVarious Articles, of which the following is a specification, referencebeing had to the accompanying drawings.

My object is to construct various small articles without laborious artsby the adjoining together the parts composing them by a framing-rib; andmy invention relates to the metallic rib which I use in making sucharticles as mica lamp-chimneys, fruit boxes, lanterns, paper boxes,butter-trays, retail oyster-pails, or similar articles made of panels orparts of paper, cut sheet wood, or like materials, that need firmjoining-pieces; and the nature of my invention will be apparent as Idescribe it.

Figure l is a very much enlarged cross-sectlon of one of my ribs orframing-pieces. Figs. 2 are sections of various formsofcorner-pieces orribs of the actual sizes used, or nearer their actual size. Fig. 3 is aview of the top wire band for such articles; and Figs. 4 are side viewsof the rib; and Figs. 5 show the tenon andmortise and riveting-band ofthe rib-tenon for both the base and top of such articles. Fig. 6 is thetop of an article having a larger top than base, with the upper part ofthe upright rib a cut away to show the loop (I of the wire 0 inserted inthe space a of the rib. Fig. 7 is a View of the right-hand end corner ofone side of a butter orberrybox made of thin sheets of wood heldtogether by ribs a a a-the sides and bottom made of the thin panels ofwood in the spaces a of the ribs a, and having the tenon extensions ofthe various ribs a inserted at the top and bottom into the spaces a ofthe upright ribs, as shown, parts of the upright rib a being cut away toshow theirinsertion.

In the figures, a a are the framing-ribs or corner-pieces for connectingtogether the articles spoken of. In their use the mica, glass, wood, orpaper panels or parts j are placed in the panel-spaces a a, and thebottoms ofthe ribs are made fast to the base-plate b by a tenon, i,which is formed by cutting away all the rib except one side andinserting the tenon in a slot or mortise, i, Fig. 5, where it is bent orriveted, as shown, thus securing the rib to the base or bottom of thearticle. The same tenon or extension *5 and mortise or aperture 2" andsecuringor clinching are adapted to the top of various articles when itis desirable to use it there; or the top of the various articles areheld together by a wire band, 0, with folded bendings d, as seen in Fig.3. These folds go into the cavities of the ribs, as will be soonexplained, and which band may be concealed in an ornamental top border.Each corner of the article thus made is composed of a single pieceofsheet metal-as, i or example, tin-plate-bent or folded on itself in amanner soon to be described, thereby forming flanged lips, channels, orpanel-spaces a, in which the edges of the panels are inserted and firmlyheld.

The manner of folding the strips of sheet metal is seen by the forms Iprefer in Figs. 2. Many others might be shown. ByAis shown the sectionof natural size,which is represented enlarged in Fig. 1. To produce itwe will suppose we have astrip ofthin tin-plate about fiveeighths of aninch wide and any convenient length, and that the bendingis commenced atits edges. Then each edge is bent over on itself, as shown, making twolips or channels about an eighth of an inch deep, in which thepanel-edges are placed,which are the spaces a. Then there are made oneach side of the longitudinal middle line two angular bendings, alsoshown, making the base of a triangle, about an eighth of an inch wide,and these bendings are continued until the apex of the triangle by itstwo sides touch, and amiddle space, a, is produced, the space in whichthe folds cl of the wire a are inserted. Thus by the four angles shownand the five or six plain surfaces between the curves, folds, or angles,or extending from the said angles is made the rib or framing-piece shownand described. The said curves, folds, or angles are marked 0 e e e andthe plain surfacesff f f f f, and in some formsf, by which the rib a ismade, which has, as has been said, the spaces a, for panels, and thespace o, for stitfenin g the rib, as well as the insertion of thejoining folds or tenons. Thicker and wider strips of sheet metal areused for coarser pieces or ribs of coarser articles. It need hardly besaid that the loops cl of the wire 0 are made at the distance apart ofthe upper ends of the ribs. The loops have enlarged lower ends, with orwiththe ribs banded by the wire. Of course the same wire band can, ifnecessary, be used at the base of the article made.

In Figs. 2 are seen other forms of the folded strip of sheet metal, theforms marked B D E being desirable and their construction is evidentfrom what has been said of the form A, whether made by hand or machineryIt is also evident that the rib a can be used by one of its spaces a forbands or binding at the top or bottom of an article, the tenonsz' beingplaced in the spaces a'. The form B is for parallel panels, and those ofAOD E for panels at right angles to each other; and on the sameprinciple joining of acute or obtuse angles is made. By these formsvarious articles such as are coming into general use are easily madewith ac curacy and success. The ribs, if rolled or flattened, makeobtuse angles, and if compressed make acute angles, for thepanels heldby them and vertical obliquity eitherinward or outward of the panelmakes no difference with the use of the ribs, bands, or tenons, exceptslight adjustments at the ends, tenons, or folds.

The further uses and advantages of my invention are apparent.

I claim- The ribs a, holding together the sides of the panels of boxesand other like articles, in combination with binding-plates b, whichhold the ends of the ribs, said ends being inserted through and foldedon said plates, as set forth.
